I decided to watch this movie for two reasons. The first being that I'm a fan of Jang Hyuk, so when I saw he was the male lead in the movie I was like "ok let's watch this movie". The second reason is that I actually enjoy watching or reading things that deal with psychology, so it convinced me even more to watch it.

So what can I say about this movie ? It was a really pleasant watch.
First of all, I have to talk about the acting. Everyone did a good job considering their character, which were not made to display all of their talent except for one character: Yong Eun. Jo Bo Ah did an excellent, I would even say a brilliant job in portraying the twisted Yong Eun, it totally blew me away, which is one of the reason I liked this movie.

Now about the story, as you may have read on the summary above, it revolves around Jun Gi a stressed out PE teacher which one day gives in to his emotions and do something that will throw his life into a spiral of chaos BUT it's not only that, it's not only the story of a PE teacher and a "yandere" student, it has (at least I think it has) another underlying meaning that you will understood throughout the movie and especially thanks to the last scene, which is why I would recommend anyone to watch this movie closely up until the end.

To conclude this review, I would recommend this movie, it might not be the best movie out there, but it's still a really good movie to watch
